"Health Technology Assessment (HTA) is defined as a multidisciplinary process that uses explicit methods to determine the value of a health technology at different points in its lifecycle. The purpose is to inform decision-making in order to promote an equitable, efficient, and high-quality health system. The definition reflects that facts and values are intertwined in HTA. This means that HTA should be considered as a type of policy analysis, wherein the assessment of safety, clinical and cost implications of health technologies, as well as their wider ethical, legal, social, organizational, environmental and other implications is conducted from the view that these aspects are closely interrelated, and wherein stakeholders are involved in a more productive way throughout the process of HTA. Acknowledging this holds the potential of conducting assessments of health technologies in a way that supports deliberative democratic decision making. In the 2018-2021 EU Erasmus+ strategic partnerships project “VALues In Doing Assessments ofhealthcare TEchnologies” (VALIDATE), a consortium of seven academic and HTA organizations have developed an approach to HTA that allows for the integration of empirical analysis and normative inquiry. The VALIDATE handbook: an approach on the integration of values in doing assessments of health technologies offers the reader an opportunity to get acquainted with the theoretical considerations and apprehend the associated practical and organizational implications of this approach. It offers those interested in HTA to integrate empirical analysis and normative inquiry in a transparent way."

The growth of personalised medicine and patient partnerships in biomedical research are reshaping both the emotional and material intersections between human patients and animal research. Through tracing the creative work of patients, publics, scientists, clinicians, artists, film-makers, and campaigning groups this chapter explores how ‘patient voices’ are being rearticulated and represented around animal research. The figure of ‘the patient’ has been a powerful actor in arguments around animal research, mostly ‘spoken for’ by formal organisations, especially in publicity material making ethical justifications for the need and funding of medical research. Here, patient voices make corporeal needs legible, gather expectations and resources, and provide the horizon for embodying future hopes. However, the accessibility of digital media, alongside local institutional experiments in openness, is creating alternative spaces for voicing patient interfaces with animal research. On research establishment websites, and elsewhere, patients’ perspectives are emerging in short films, taking up positions as narrators, tour guides, and commentators, inviting the public to follow them into these previously inaccessible spaces. The embodied experience of patients, sometimes severely affected by the current absences in biomedical research, are used to authorise their presence in these places, and allow them to ask questions of animal researchers. The films are powerful and emotional vehicles for voicing patient experiences and opening up animal research. They also refigure the affective responsibilities around animal research, resituating a public debate around ethics within the body of the patient. The future expectations personified in the abstract figure of the patient, are rendered turbulent in the ambiguous corporeal encounter between human and animals undergoing similar experiences of suffering.

This chapter adopts a historical perspective to explore how material infrastructures have structured human–animal relationships within the biomedical “animal house,” c.1945 to the present. It argues material infrastructures serve to structure the multiple values that have informed and shaped human–animal relations within the experimental biomedical sciences. By exploring how multispecies sociocultural relations performatively shape and are shaped by the physical infrastructures that make up lived relations and shared labor in the animal house and laboratory, the chapter charts how “multispecies relations” form a dynamic, situated and emergent “moral economy” wherein the moral economy cannot be separated from factors that would properly be associated with a political economy of animal-dependent experimental science.

Because of many misconceptions, the biological drug manufacturing industry does not fully utilize disposable components, despite their wide availability. These misconceptions include concerns for the quality of materials, running costs, scalability, the level of automation possible, and the training of staff needed to include these components in existing bioprocessing systems. Not fully realizing the long-term benefits, many manufacturers are unwilling to discard investments made in fixed equipment and traditional stainless steel systems. Regulatory and environmental concerns, however, will eventually compel manufacturers to adopt disposable systems. Making a strong case for disposables, Disposable Bioprocessing Systems demonstrates the true potential of these systems. Written by a researcher and professor with hands-on experience in designing, establishing, and validating biological manufacturing facilities worldwide, and creating model facilities using maximum disposable technology, this book is the first comprehensive introduction to understanding disposable systems. It gives an overview of the current state of the disposable bioprocessing industry, resolves all controversial issues, and guides readers in choosing disposable components that meet their needs. An important chapter on safety addresses facts and myths about the use of plastics and elastomers—including the issue of leaching—and how to ensure regulatory compliance. Helping readers understand their choices, the book describes the equipment and systems available to prepare the starting materials for the manufacturing of biological drugs—from disposable containers to filters. The author also discusses costs, regulations, and concerns about waste disposal, and shares his predictions for the future of the disposable bioprocessing industry. A practical manual for those interested in the transition to disposable systems, this book will also interest students of bioprocessing. It offers a timely view of disposable bioprocessing technology as a "game changer" that will facilitate developing new drugs and conducting research in the emerging field of stem cells and gene therapy.

I have been teaching courses on experimental techniques in nuclear and particle physics to master students in physics and in engineering for many years. This book grew out of the lecture notes I made for these students. The physics and engineering students have rather different expectations of what such a course should be like. I hope that I have nevertheless managed to write a book that can satisfy the needs of these different target audiences. The lectures themselves, of course, need to be adapted to the needs of each group of students. An engineering student will not qu- tion a statement like “the velocity of the electrons in atoms is ?1% of the velocity of light”, a physics student will. Regarding units, I have written factors h and c explicitly in all equations throughout the book. For physics students it would be preferable to use the convention that is common in physics and omit these constants in the equations, but that would probably be confusing for the engineering students. Physics students tend to be more interested in theoretical physics courses. However, physics is an experimental science and physics students should und- stand how experiments work, and be able to make experiments work. This is an open access book. ; I have been teaching courses on experimental techniques in nuclear and particle physics to master students in physics and in engineering for many years.

Analysis of medical data using engineering tools is a rapidly growing area, both in research and in industry, yet few texts exist that address the problem from an interdisciplinary perspective. Epileptic Seizures and the EEG: Measurement, Models, Detection and Prediction brings together biology and engineering practices and identifies the aspects of the field that are most important to the analysis of epilepsy. Analysis of EEG records The book begins by summarizing the physiology and the fundamental ideas behind the measurement, analysis and modeling of the epileptic brain. It introduces the EEG as a measured signal and explains its use in the study of epilepsy. Next, it provides an explanation of the type of brain activity likely to register in EEG measurements, offering quantitative analysis of the populations of neurons that contribute to both scalp and cortical EEG and discussing the limitations and effects that choices made in the recording process have on the data. The book provides an overview of how these EEG records are and have been analyzed in the past, concentrating on the mathematics relevant to the problem of classification of EEG. The authors use these extracted features to differentiate between or classify inter-seizure, pre-seizure and seizure EEG. The challenge of seizure prediction The book focuses on the problem of seizure detection and surveys the physiologically based dynamic models of brain activity. Finally, the book addresses the fundamental question: can seizures be predicted? Through analysis of epileptic activity spanning from 3 hours to 25 years, it is proposed that seizures may be predictable, but the amount of data required is greater than previously thought. Based on the authors’ extensive research, the book concludes by exploring a range of future possibilities in seizure prediction.

The ability of non-equilibrium plasmas to modify surfaces has been known for many years. And a promising way to perform surface modifications without altering the bulk properties is plasma polymerization since this technique is versatile and can be applied to a wide range of materials. Plasma polymer films usually show good biocompatibility when compared to classical biomaterials. The possible biomedical use of plasma polymers motivates the study of their behavior during storage and in aqueous environment. Therefore, it is of major importance to understand the change of properties of these plasma polymers over time and when in contact with certain fluids. Recently, plasma polymer gradients (surfaces that display a change in at least one physicochemical property over distance) have attracted significant attention from the biomedical filed where the interaction of cells with a material surface is of major interest. This chapter discusses biomaterial functionalization via plasma polymerization focusing on their use in the biomedical field as well as their aging and stability behaviors. Plasma polymer gradients as valuable tools to investigate cell-surface interactions will also be reviewed.

The repair of peripheral nerve traumatic lesions still represents a major cause of permanent motor and sensory impairment. In case of substance loss, a nerve guide should be used to bridge the proximal with the distal stump of the severed nerve. The effectiveness of hollow nerve guides is limited by the delay of axonal growth due to the absence of a regeneration substrate inside the conduit. To fasten up nerve regeneration, nerve guides should thus be enriched by a luminal filler. In this study, we investigated, in a 12-mm rat sciatic nerve defect experimental model, the effectiveness of chitosan-based conduits of different acetylation filled either with a hyaluronic acid gel (NVR gel) or with a magnetic fibrin hydrogel, in comparison with traditional autografts. Results showed that all types of artificial nerve conduits led to functional recovery not significantly different from autografts. By contrast, morphological and morphometrical analyses showed that the best results among nerve guides were found in medium degree of acetylation (DAII: ∼5%) chitosan conduits enriched with the NVR gel.

Tissue engineering has offered wide technologies for developing functional biomaterials substitutes for repair and regeneration of damaged tissue and organs. Biomimetic materials with their inherent nature to mimic natural materials are possible through the recent advances in the fabrication technology. With the help of porous or dense implants made with biodegradable materials, it is possible to incorporate different vital growth factors, genes, drugs, stem cells and proteins. In this review, we presented various fabrication methodologies of biomimetic and bioactive scaffolds for tissue engineering applications. An overview of the nanocomposites of biomaterials is presented. Further an example of one of the hybrid nanocomposite material is given for additive manufacturing.
